Yini i-API 5L?

I-API 5L ngokuvamile ibhekisela ekusetshenzisweni kwezinga lamapayipi ensimbi, okuhlanganisa izigaba ezimbili eziyinhloko:amapayipi ensimbi angenamthungofuthiamapayipi ensimbi ashiselwe. Njengamanje, izinhlobo ezivame ukusetshenziswa ezishiselwe ipayipi lensimbi kumapayipi kawoyelaamapayipi ashiselwe i-arc angaphansi kwe-spiral(IPHyiphi le-SSAW),amapayipi ashiselwe i-arc longitudinal ngaphansi kwamanzi(LSAW PIPE), kanyeukumelana nogesi amapayipi ashiselwe(ERW). Amapayipi ensimbi angenamthungo ngokuvamile akhethwa lapho ububanzi bepayipi bungaphansi kuka-152mm.

 

I-GB/T 9711-2011 ejwayelekile kazwelonke, Amapayipi Ensimbi Yezinhlelo Zokuthutha Amapayipi e-Petroleum and Natural Gas Industries, yathuthukiswa ngokusekelwe ku-API 5L.

 

I-GB/T 9711-2011 icacisa izidingo zokukhiqiza zamapayipi ensimbi angenamthungo nashikelwe asetshenziswa ezinhlelweni zokuthutha zamapayipi e-petroleum negesi yemvelo, ahlanganisa amazinga amabili wokucaciswa komkhiqizo (PSL1 kanye ne-PSL2). Ngakho-ke, leli zinga lisebenza kuphela kumapayipi ensimbi angenamthungo futhi ashiselwe ukuhambisa uwoyela negesi futhi akusebenzi kumapayipi ensimbi.

 

Amabanga Ensimbi

Amapayipi ensimbi e-API 5L asebenzisa amabanga ezinto ezingavuthiwe ahlukahlukene ahlanganisa i-GR.B, X42, X46, X52, X56, X60, X70, X80, namanye. Izinsimbi zamapayipi ezinamabanga X100 kanye no-X120 sezithuthukisiwe. Amamaki ensimbi ahlukene abeka izidingo ezihlukile ezintweni ezingavuthiwe nezinqubo zokukhiqiza.

 

Amazinga Ekhwalithi

Ngaphakathi kwezinga le-API 5L, ikhwalithi yensimbi yepayipi ihlukaniswa njenge-PSL1 noma i-PSL2. I-PSL imele Izinga Lokucaciswa Komkhiqizo.
I-PSL1 icacisa izidingo zekhwalithi ezijwayelekile zensimbi yamapayipi; I-PSL2 yengeza izidingo eziyisibopho zokwakheka kwamakhemikhali, ukuqina kwenotshi, izakhiwo zamandla, nokuhlolwa kwe-NDE okwengeziwe.
